Multicolor emergency vehicle light
First Claim
1. An emergency vehicle light comprising:
- a base adapted to be mounted on an emergency vehicle;
lamp means on the base for emitting a beam of light;
reflector means external to and projecting laterally beyond the base having at least three reflector segments arranged generally along a parabolic curve having a focal point coaxial with said lamp means, each reflector segment being adapted to reflect the beam of light emitted by said lamp means for observance by an observer remote from said vehicle; and
means for effecting relative movement between said beam and said three reflector segments whereby said beam of light emitted by said lamp means is adapted repetitively to traverse said reflector segments in sequence whereby said observer is adapted to observe at least three discrete flashes of light in a repetitive sequence after each traverse of said reflective segments by said beam with each flash corresponding to a reflection of said beam off a respective reflector segment.

Abstract
A base adapted to be mounted on a vehicle supports a light source for generating a rotating light beam. A dome-shaped lens is positioned on the base over the light source to form an enclosure for the light source. A coating may be located on the top of the lens to prevent light passing therethrough and into the passenger compartment. Multiple flashes are created by a reflector positioned adjacent the rear portion of the lens to reflect the rotating beam as a plurality of discrete flashes within a sector relative to the base. A filter generally having a contour of the front portion of the lens may be mounted thereon. The multiple flashes may be of different colors depending on the range of wavelength of light transmitted by the lens and filter and reflected by the reflector. A person viewing the light sees at least four discrete flashes of light which may be of varying colors.

12. An emergency vehicle light comprising:
-
a base adapted to be mounted on a vehicle; a light source on the base adapted to emit a beam of light; means for rotating the light beam relative to the base about an axis; lens means on the base enclosing the light source, said lens means being adapted to transmit light within a first wavelength range; and reflector means positioned external to and releasably mounted on the lens means for reflecting light from the light source, the reflected light being within a second wavelength range different from said first wavelength range whereby, on rotation of the light beam, a person viewing the emergency vehicle light is adapted to see discrete flashes of light of different colors. - View Dependent Claims (13, 14, 15)

25. An emergency vehicle light comprising:
-
a base adapted to be mounted on a vehicle; a light source on the base adapted to emit a beam of light; means for rotating the light beam relative to the base about an axis; connecting means including a wire for connecting the light source to a power supply located outside said enclosure; a dome-shaped lens adapted to be positioned on the base over the light source to form, in conjunction with the base, an enclosure for the light source, said lens having a top wall and a side wall with a bottom edge projecting below the base; and strain relief means for securing said wire against strain adjacent the location where the wire exits said enclosure, said strain relief means comprising a notch extending upwardly from said bottom edge for receiving said wire therethrough, said notch being so sized and configured that the lens is adapted to press the wire against the base when the lens is mounted on the base. - View Dependent Claims (26)
